Final answer:
Before the Beatles' hits, rock 'n' roll was the dominant genre on the pop charts, with artists such as Little Richard and Bill Haley leading the way, integrating various musical influences and breaking down racial barriers in the music industry.
Step-by-step explanation:
The artists and genres that dominated the pop charts prior to the Beatles' early hits were primarily from the rock 'n' roll genre. This genre was pioneered by influential artists such as Little Richard, Bill Haley, Chuck Berry, Fats Domino, and Buddy Holly. Rock 'n' roll, a groundbreaking combination of rhythm and blues, country, jazz, and other styles, captivated teenagers and became a lucrative part of the entertainment industry.
The cultural impact of rock 'n' roll was substantial, leading to both controversy and profitability due to its rebellious nature and integration of African American music into the mainstream. Artists like Elvis Presley followed in the footsteps of African American performers, bringing rock 'n' roll to a wider audience and bridging racial divides in music. By the time the Beatles arrived on the scene, rock 'n' roll had set the stage for their success and the evolution of the pop genre.
